Cast aluminum "Y" connector for 4" diameter hose. The 200-60 hose will thread into the "Y" connector. Please keep in mind if you use this connector make sure you use relatively short runs of hose if you are porting to two different grinders.
IMPORTANT, PLEASE READ: By using a "Y" connector you will reduce the CFM (cubic feet per min) of draw by the dust collector in half approximately. For example at 4" the MAG-200 has a draw of 400 CFM, with the "Y" would would roughly have two sources at 200 CFM each. Using very long runs of hoses will also reduce performance.
